The Bivalvia Class, is widely represented in marine ecosystems and is economically important;this research focused on this class and was carried out by sampling the rocky intertidal zone of seven sites located in the Marina Region Priority No. 32, Guerrero, Mexico, where the National Commission for the Knowledge and Use of Biodiversity reported lack of knowledge on marine species living there. The objectives were to examine species richness associated with the rocky intertidal zone, determine how the community is composed by the representation of families based on species richness and abundance, know the distribution of the species, analyze the structure sizes of populations and estimate the diversity index. Sampling was conducted at seven sites;the sampling unit was one square meter and the sampling area was 10 m2. 32 species were identified. Four species are new records for the Mexican Pacific Transitional: one for the state of Guerrero and one for Marine Priority Region 32. Arcidae and Mytilidae Families were better represented in species richness and Chamidae Family was the best represented in abundance. Chama coralloides was considered to be the representative species of the area;Striostrea prismatica showed the greatest size. The diversity index was estimated (H' = 3.65 bits/individuals). Species richness is high and corresponds to that expected in a tropical area.

The community of mollusks at three rocky intertidal zone in Oaxaca, Mexico was analyzed. Two samplings per site were conducted. At each sampling the inspected area was 10 m2. The sampling unit was 1 m2. 5862 specimens were examined. 68 mollusks species were identified. The families better represented in species richness were: FISSURELLIDAE, MURICIDAE, LOTIIDAE, MYTILIDAE, CHAMIDAE, ISCHNOCHITONIDAE y CHITONIDAE. The species that had the greatest density were Lottia discors, Siphonaria palmata, Lottia acutapex, Chormoytilus palliopunctatus, Brachidontes adamsianus, Chton articulatus e Ischnochiton muscarius. The species with the widest distribution represent 11.76%. With irregular distribution was found in 58.82% of the species. The gastropod Crucibulummonticulus, the bivalve C. palliopunctatus and the polyplacophoran C. articulatus had the greatest size. The value of diversity index was H’ = 4.29 bits/ind. and J’ = 0.72. The mollusks community in the rocky intertidal zone study sites is characterized by small size, because they rarely exceed seventy millimeters. The values of H’ and J’ indicate that the mollusk community in the study area has a high diversity and high uniformity, corresponding to mature and stable communities in a tropical region.

Plicopurpura pansa is a cultural resource with economic importance since ink can be extracted from it to dye clothes. This snail inhabits the rocky intertidal zone of Mexican Pacific, is found attached to rocks in crevices and holes. The objective was to analyze the P. pansa population structure in Costa Chica of the State of Guerrero based in density, sex ratio, size and weight, besides to realize observations on mating and recruitment, for which quarterly sampling was made during an annual cycle in three beaches. The density was 4.83 snails/m2. Sex ratio ranged from 0.76:1.00 to 1.00: 0.96 (F:M). Average size was 20.91 mm. The best represented sizes in females were from 10.5 to 28.5 mm and in males 13.5 to 28.5 mm. Averaged weight was 1.99 g, females showed a coefficient of variation in weight of 96.53%. Recruitment occurred for the entire year. In December 2006 and September 2007 a larger frequency of recruits was shown. Sex ratio showed a 1:1 tendency. Snail population was characterized by being small sized and in high densities. Weight variations in females were found related to their reproductive cycle.

Acapulco, Mexico has a coastline of 62 km where large areas of rocky substrate inhabited by organisms such as the GASTROPODA Class can be found. Conidae (Fleming, 1822) Family is among the members of this Class, which has been poorly studied in the Mexican Pacific, despite their biomedical potential. This research was carried out in the rocky intertidal of nine sites in Acapulco. The objectives were: 1) Prepare an inventory of species associated with rocky intertidal of Conidae family, 2) examine the composition of the family based on two criteria: a) species richness and b) abundance, 3) determine the geographical distribution and 4) analyze the size composition. The unit sampled was 1 m2 and the sampled area was 10 m2 persite. A total of 97 organisms were analyzed, corresponding to two subfamilies, five genera and five species. The Puncticuliinae (Tucker & Tenorio, 2009) subfamily had higher species richness, abundance and frequency of occurrence. The most abundant and most common species were Harmoniconus nux (Broderip, 1833) and Gladioconus gladiator (Broderip, 1833) both showed regular distribution. The size structure found for Conidae family is similar to what has been reported in other research. For the first time G. gladiator is being reported for the state of Guerrero.

The GASTROPODA class, one of the best known marine environments, is formed by a large number of species and the shape of their shell structure varies greatly. These mollusks are distributed from the intertidal zone all the way to the abyssal zone, and there are also swimming and floating species. This research was conducted at seven sites, located in the Marina Priority Region 32 (MPR 32), located in the State of Guerrero, Mexico. The aim of this report is to document the scope of the geographic distribution of the 34 species of GASTROPODA class. 11,263 total specimens were analyzed. 108 species were identified, of which four species are new records for Mexico, 15 for the Transitional Mexican Pacific, 11 for the State of Guerrero and four for the MPR 32. Here we report a significant number of new records of species of class GASTROPODA found on the rocky intertidal zone of the MPR 32. The reporting of these new records, demonstrates the need to focus research efforts on the study of marine diversity, since knowledge in this respect is quite incomplete, especially regarding marine mollusks, a fact that has been reported by the National Commission for the Management and Use of Biodiversity.

Introduction: Uterine leiomyomas, or fibroids, are prevalent benign tumors affecting up to 70% of reproductive-age women in the United States, significantly impacting productivity and quality of life. Despite their commonality, the epidemiology and clinical patterns of leiomyomas in Puerto Rico remain inadequately researched. Methods: This study conducted a secondary data analysis using clinical, menstrual cycle characteristics, and demographic data from self-administered questionnaires of women undergoing diagnostic laparoscopy for endometriosis in Puerto Rico. Chi-square tests and t-tests analyzed categorical and continuous variables, respectively (p Results: Among 1,610 endometriosis cases, 312 included uterine fibroids. Prevalence estimates were 10.3% (40 years). Primiparous women averaged 22.14 years, with 40.71% having 2 - 3 pregnancies and 26.28% experiencing miscarriages. Symptoms included infertility (29.5%), dyspareunia (40.7%), severe pain (50%), and dysmenorrhea (75.6%). Comorbidities included ovarian cysts (52.2%) and abnormal uterine bleeding (37.8%). Conclusions: Advanced age, parity, and comorbidities like diabetes and hypertension were prevalent in our cohort. Understanding the epidemiological profile of women living in Puerto Rico with uterine fibroids is crucial for improving diagnostic awareness and enhancing patient care.
